Get POVRay-source file from addon
The exporter's wiki page contains all necessary information to get you started in several languages,

It is possible to edit the options of where and how to write the pov file, when "AUTO"(car icon) is unchecked in render tab's INI Options panel

If you uncheck Delete file option, you will be able to open the rendered pov file from the temporary folder, or the folder of your choice if any has been specified.

Some topics include command line switches to pass parameters as you would through the command prompt when launching POV from a terminal or from ini files.
